Definitions

  • the invention relates to a supplementary kit for at least one job of twisting or cabling machines according to the preamble of claim 1. Furthermore, the invention relates to a twisting or cabling machine comprising such a supplementary kit.
  • These counterforces are formed, for example, from the sum of the frictional forces in the cabling spindle, on the storage disk, on the thread travel path and by a thread brake.
  • the thread brake is usually adjustable, so that the different running and power conditions can be taken into account depending on the titer, type of thread or thread preparation.
  • hysteresis brakes are often used as thread brakes, which, equipped with specially shaped friction wheels, enable finely metered and gentle use of the braking forces.
  • twisting or cabling machines with devices for adjusting the thread tension of the inner thread and / or the outer thread are in various patent applications, for example in the DE 41 21 913 A1 , in the DE 100 30 888 B4 or in the EP 1 167 597 B1 partly described in great detail.
  • the US 2006/042220 A1 describes a yarn processing machine with a multifilament yarn manufacturing unit and a yarn quality assurance method in the production of a multifilament yarn with a thread tension control module, which is a component that is absolutely necessary for the operation of the textile machine in question.
  • the DE 100 30 888 B4 or the EP 1 167 597 B1 known cabling spindles for example, on a Storage disc is dispensed with and instead the thread tension is essentially regulated by a pot rotating with the cable spindle, which largely prevents the formation of a free thread balloon except for a remaining balloon.
  • the known cabling spindles are each also equipped with workplace-specific devices for adjusting the thread tension of the outer thread, which can be designed differently.
  • this device is either designed as a thread brake or as a device with which the outer thread can not only be braked but also actively promoted.
  • the through the EP 1 167 597 B1 Known thread influencing device is preferably also designed as an active delivery unit.
  • a cabling spindle in which the thread tension of an inner thread and an outer thread is influenced by means of adjusting devices in such a way that the threads in the cabling point have the same thread tension and the same thread speed.
  • the inner thread is acted upon by an inner thread brake, the braking effect of which is controlled as a function of the outer thread / balloon thread tension.
  • the outer thread is inserted centrally into the cabling spindle and exits radially on a rotating storage disk which is attached to the cabling spindle below the twisting plate.
  • the outer thread wraps around the storage disk at least partially before the thread is transferred over the outer edge of the twist plate into a free thread balloon.
  • DE 10 2008 033 849 A1 have already been proposed to set the feed speed of the outer thread by means of an active thread feed mechanism so that no thread storage occurs, but the thread tension assumes a value that minimizes the diameter of the free thread balloon encircling the spindle, depending on the geometry of the spindle.
  • the invention is based on the object of developing a supplementary kit which makes it possible to significantly reduce the energy consumption even in the case of twisting or cabling machines which are already in use.
  • a retrofittable supplementary kit according to the invention has the particular advantage that, in a relatively simple and inexpensive manner, even workplaces of twisting or cabling machines already in use can be subsequently modified so that their energy consumption is significantly reduced.
  • This means that many older twisting or cabling machines can be raised relatively easily in terms of energy consumption to a standard that almost corresponds to the standard of twisting or cabling machines, as in the DE 10 2008 033 849 A1 described, equipped.
  • the supplementary kit has a drive that can be controlled in a defined manner for rotating a thread friction wheel.
  • the thread speed and thus the thread tension of the outer thread running over the friction wheel can be finely adjusted by means of the drive.
  • the supplementary kit according to the invention always ensures gentle treatment of the outer thread.
  • the continuous adjustment of the thread speed also reliably avoids fluctuations in the delivery of the thread, which can lead to breakage of the thread or collapse of the thread balloon.
  • the thread speed is used as a manipulated variable for the thread tension, the thread tension being determined before or after the formation of the thread balloon on the spindle.
  • the power consumption of a drive used to rotate the cabling spindle can also be used as the manipulated variable for the thread tension. This means that the thread speed influences the diameter of the free thread balloon via the thread tension, the dimension of which is decisive for the power consumption of the associated drive.
  • a combination of the manipulated variables mentioned is also conceivable in order to regulate the thread tension as precisely as possible, the necessary monitoring of the thread tension preferably being able to be carried out electronically and / or mechanically.
  • the control device for the drives of the supplementary kit can be integrated into the existing central control device of the machine.
  • the supplementary kit as described in claim 2, has two separately controllable drives, to each of which a thread friction wheel is connected to act on an outer thread.
  • Such a supplementary kit can be fixed via the housing on the walls of neighboring workplaces.
  • Such a training has the great advantage that the outer threads of two neighboring jobs are conveyed at the same time can be, whereby a separate treatment of the drives a separate treatment of the outer threads is still possible.
  • the drives are connected via control lines to workstation-specific controller boxes which are connected by means of a data bus to a centrally arranged control device of the twisting or cabling machine.
  • the drives can be controlled in such a way that the thread speed of the outer threads required for this is always guaranteed. This means that the thread tension of the outer threads is adjusted by the drives via the thread speed in such a way that the associated thread balloons always have their minimum diameter, which is predetermined by the diameter of the bobbin receiving pot of the associated cabling spindle.
  • the drives of the supplementary kit or of the thread delivery mechanism can influence the thread speed of the outer threads both in the sense of "accelerating” and in the sense of "braking". In this way, a safe and simple adjustment of the thread tension of the outer threads required in each case is possible.
  • the drives are preferably designed as stepper motors.
  • Such stepper motors are well-proven large series parts in drive technology that are inexpensive to buy in retail.
  • the thread friction wheels of the supplementary kit are arranged in the thread travel path of two outer threads such that they are positioned behind the thread friction wheels of the existing job-specific thread brakes in the thread running direction.
  • the thread brakes at the work station are preferably designed as hysteresis brakes which can be controlled in a defined manner.
  • hysteresis brakes have the particular advantage that the force / torque generated is not speed or speed-dependent, that is, a hysteresis brake always has a steady braking torque from standstill to a design maximum speed, which of course can be set exactly if necessary is.
  • control device for the drives and / or the workstation-specific controller boxes is designed such that they set the respective thread tension of the outer thread only after starting up a workstation and during the subsequent twisting or cabling operation via the thread delivery mechanism of the supplementary kit.
  • control device for the drives and / or the controller boxes set the thread tension of the outer threads by means of the supplementary kit according to the invention during most of the time of the cabling operation, but not during the start of the work stations.
  • the workplaces are brought up to operating speed in a tried and tested manner using the thread brakes already present in the workstation.
  • a twisting or cabling machine 1 is shown in a schematic front view.
  • Textile machines of this type each have a multiplicity of identical work stations 2 in the region of their machine longitudinal sides.
  • textile machines of this type generally have a drive and operating unit 8 arranged on the machine end, in which, for example, the required energy devices, various drives and a central control device 32 are installed.
  • the twisting or cabling machine 1 also has a bobbin transport system, the schematically illustrated delivery point of which is identified by the reference number 10.
  • the work stations 2 of twisting or cabling machines 1 with outer thread feeder each have a creel 3, which serves to receive at least one first supply spool 4, from which a so-called outer thread 5 is drawn off.
  • Such workplaces 2 furthermore each have a cabling spindle, which is not shown in the figures of the present application for reasons of better clarity, which is driven by a spindle drive.
  • a spindle drive can be a motor that drives the cabling spindle directly, or an indirect drive, for example a belt drive.
  • the cabling spindle carries, as usual, on a stationary bobbin bottom arranged on the cabling spindle, also a second supply bobbin, from which a so-called inner thread is drawn off overhead, above the Kablierspindel a balloon eyelet or a compensation system 7 is supplied.
  • this thread tension influencing device essentially consists of a thread brake 11 which is preferably designed as a hysteresis brake and an active thread feed mechanism 13 arranged in a retrofittable supplementary kit 12.
  • the hysteresis brake 11 is connected to an existing control device 32.
  • a further control device 9 is provided, which can be integrated into the existing control device or can be designed separately. Alternatively, several control devices can be provided, which are arranged, for example, in sections.
  • the control device 9 is coupled via a data bus 28 to controller boxes 9 'at the work stations 2, which in turn are equipped with measuring and regulating devices in order to regulate the thread speed and thus the thread tension in a work station-specific manner.
  • the respective hysteresis brake 11 and the supplementary kit 12 are, as usual, installed in the thread running direction F in front of the cabling spindle.
  • the compensation system 7 is the cabling point, in which the outer thread 5 and the inner thread converge.
  • a pull-off device 17 is arranged above the cabling point, by means of which the cabled Thread is drawn off and fed to a winding device 19 via a compensating element, for example a dancer arm 18.
  • the winding device 19 has, as usual, a drive roller 20 and a thread traversing device 21.
  • the cabled is by means of the thread traversing device 21 Thread wound onto a cross-wound bobbin 23, which is driven by the drive roller 20 by frictional engagement and held in a bobbin frame 22.
  • the retrofittable supplementary kit 12 has, as in particular from the Figures 4-6 evident about a Housing 26, which can be fixed, for example detachably, to the walls 24, 25 of work stations 2 of a twisting or cabling machine 1, for example by means of screw bolts 31 or the like.
  • Supported drives 27A and 27B are mounted in the housing 26 in corresponding bearing devices, on each of which a thread friction wheel 14 is arranged on the motor shaft.
  • the motor shafts of the drives 27A, 27B are preferably arranged at an incline such that a trouble-free transfer of the outer threads 5 from the thread friction wheels 14 of the thread feed mechanisms 13 to the deflection rollers 15 is ensured.
  • the housing 26 In order to prevent the drives 27A, 27B from overheating, the housing 26 also has ventilation slots 29.
  • the drives 27A, 27B which specify the thread speed and thus also the thread tension of the outer threads 5 via the thread friction wheels 14, are furthermore via control lines 28 'in each case to controller boxes and these in turn via a data bus 28 to a control device 9 and (not shown) Supply lines connected to the energy supply device of the twisting or cabling machine.
